Make two graphs of your data. On one graph plot the data from the pure water. On the other graph plot the data from the salt solution. On both plot temperature on the y-axis and time on the x-axis.
A. Record the freezing point of the pure water and the freezing point of the salt solution. B. How do these two freezing points compare?
C. What are some practical applications of freezing point depression, boiling point elevation, and vapor pressure lowering?
Questions - Part 2

What determines the texture of soil?
The amount of soil, sand, and silt in the soil. There are 13 different types of soil, but all types consist of these three components. What changes the type of soil is the amount of each component present in the soil.
What is meant by the permeability of a soil? What is porosity and how is it related to permeability?
Permeability is how water moves through soil. Porosity is the spaces between soil. They are called pores. These pores are all connected
